Typical Load Factor For Sag Mill Motor In Indonesia

Total Losses in Power Distribution and Transmission Lines

Load variation is Called load factor and It varies from 0 to 1 Load Factor = Average load in a specified time period / peak load during that time period For example for 30 days month 720 hours peak Load of the feeder is 10 MW If the feeder supplied a total energy of 5 000 MWH the load factor for that month is 5 000 MWh / 10MW x 720 =
